Burger King has no problem zinging and prodding its rival fast food restaurants. Now, the chain is encouraging fans to ‘burn’ those rivals thanks to a new app feature that sees billboards engulfed in flames.

With the ‘Burn That Ad’ campaign, anyone who launches the Burger King app in Brazil and points their smartphone at its main competitors’ ads may enjoy the sight of it being burned up instantly – in augmented reality – and turned into a BK ad. When the flames burn away, the consumer is left with a screen that tells them they’ve received a free Whopper to be savoured at the nearest restaurant.
